Performance, composting methods, environmental impacts and biosecurity of the process are evaluated for emergency disposal of cattle by research team at Iowa State University. A THREE-YEAR study was commissioned by the Iowa Department of Natural Resources to evaluate the practical feasibility, performance, environmental impacts and biosecurity of using composting for emergency disposal - should a ...

Received for publication December 12, 2007. For removal of phosphorus (P) from swine liquid manure before land application, we developed a treatment process that produces low P effluents and a valuable P by-product with minimal chemical addition and ammonia losses. The new wastewater process included two sequential steps: (i) biological nitrification and (ii) increasing the pH of the nitrified ...

For decades, arid and semi-arid regions in Africa have faced issues related to water availability for drinking, irrigation and livestock purposes. To tackle these issues, a laboratory scale greywater treatment system based on high rate algal pond (HRAP) technology was investigated in order to guide the operation of the pilot plant implemented in the 2iE campus in Ouagadougou (Burkina Faso). ...

As is known to all, catfish has quite high nutritional value due to its good taste, delicate meat quality and its better dietary therapy function for those ill nourished people. With the sweet flavor and warm in property, catfish is in favor of urinating and treating edema, becoming good item to promote lactation and essential food material ...

During the last half-century, agriculture in the upper U.S. Midwest has changed from limited-input, integrated grain–livestock systems to primarily high-input specialized livestock or grain systems. This trend has spawned a debate regarding which cropping systems are more sustainable and led to the question: can diverse, low-input cropping systems (organic systems) be as productive as ...

Interseeding cereal rye (Secale cereale L.) into a bermudagrass sod [Cynodon dactylon (L.) Pers.] can increase season-long forage production and land use efficiency. However, previous research has shown that competition from the bermudagrass sod can significantly reduce autumn forage production from cereal rye. Our objective was to determine if the application of a preplant herbicide to a ...

Nitrogen pollution resulting from agricultural activities is a major threat to the quality of the European environment. This paper aims to qualify the importance of nutritional management in reducing nitrogen pollution from intensive livestock production and to quantify its potential results where applicable. Reform of agricultural policy may achieve the economic and environmental benefits of ...

On December 17, 2010, the US National Organic Program (NOP) voted to accept the recommendation of the US National Organic Standards Board (NOSB) to prohibit engineered nanomaterials from the production, processing, and packaging of certified organic products. The decision was made with little fanfare, but has big implications. Background The NOP is a federal program managed under ...

Flaxseed (Linum usitatissiumum) also known as linseed, is thought to be one of the world’s oldest cultivated crops with evidence of cultivation dating back thousands of years. The crop is prized for its fibre and oil. The fibre, obtained from the stocks of the plant, is used to make fine linen and paper. The oil is used primarily for industrial purposes. The oil is probably best ...

A fogger is a machine which distributes chemicals such as insecticide or disinfectant into an area by means of a fine spray for killing insects and other arthropods. They are often used by consumers as a low-cost alternative to professional pest control services. The number of fogger needed for pest control depends on the size of the space needed to treat. There are different types of ...

The expansion of soy bean Soy cultivation has shown an increasing expansion throughout Argentina, Brazil, Bolivia and Paraguay, in the last decade. This remarkable increase is explained by its economical importance in the region, and as a consequence, it is difficult to regulate its progress and attenuate its potential socio-environmental impacts. In 2012, in these 4 countries the ...

Controlling birds around farm buildings can take time out of your already strict daily routines. Nuisance birds like pigeons, starlings and barn swallows don’t care about anyone’s schedule but their own. Unfortunately, sharing the barn with pest birds isn’t sanitary and the costs and dangers of birds in dairy and livestock operations can add up quickly! See how to keep ...

The McGowans’ Gaia-Wind turbine powers their water bore hole; cattle sheds; and farmhouse and has given them control over their rising electricity bills. Purchased turbine: March 2010 Average annual energy production: 21,170 kWh Predicted payback period: 5-6 years “We own a mixed livestock and arable farm in Perthshire, Scotland. About two years ago ...

The economic impact of climate change on European agriculture A new study has estimated how changes to climate might affect the value of European farmland. Based on data for over 41 000 farms, the results suggest that their economic value could drop by up to 32%, depending on the climate scenario considered- Farms in southern Europe are particularly sensitive to ...

Alan Doering doesn’t have the word “waste” in his vocabulary. As the scientist heading up the Agricultural Utilization Research Institute’s (AURI) coproduct utilization program, Doering sees crop residue, agricultural processing leftovers and biomass as products with value worth exploring. “Every leftover or coproduct has a value,” Doering says. “Our goal is to find the best use with the highest ...

With the highest cattle density in northeastern Wisconsin and urban sprawl sprawling, Brown County has accelerated its investigation into how to handle growing amounts of dairy manure and industrial wastes spread on a diminishing land base.Applying waste on limited crop acreage has led to groundwater contamination issues and pollution problems of lower Green Bay.The solution lies in a value-added ...
